ARE RUSSIAN CYBERCRIMINALS OFFERING HACKING SERVICES IN CHINA ?

On July 27, 2020, a group of threat actors published a post in the advertisement section of a prominent Chinese Darknet marketplace offering hacking services. Hacking-as-a-service offers appear frequently on Chinese underground platforms, and many actors publish these services – accompanied by varying degrees of details – on both Clearnet hacking forums and Darknet marketplaces. However, what makes this offer unique is the identification of the actors, who claim to be Russian.

WHAT INDICATES THAT THE HACKERS ARE REALLY RUSSIAN ?

  1. Several linguistic features suggest the actors are indeed non-native Chinese speakers. First, they use anachronistic vocabulary and terms rarely seen in contemporary Chinese online chatter, which is common on these forums. Two examples are the use of the term 万维网 for “World Wide Web,” and the rare version of the word “hacker” 骇客 (pronounced haike, instead of the commonly used term 黑客, pronounced heike); Second, some sentences are oddly phrased, using a combination of wrong vocabulary and/or unnatural syntax or formulation, giving the impression the text was translated from a foreign language, possibly via a machine-translation tool; Third, there are linguistic inconsistencies in the group’s posts on the forum: whereas most of the posts are written in simplified Chinese characters, used in mainland China, one is written in traditional Chinese characters, used in Taiwan and Hong Kong – this transition by the same writer is very uncommon. Furthermore, different variations of the same word or term are used simultaneously in the same post.
  2. Contact details include several Telegram, QQ and Jabber accounts, with the former two widely used by Chinese cybercriminals and hackers selling their services. However, in addition to those, they also offer their services via Yandex email service, which is rarely used outside of Russia and the former Soviet Union countries, and even less so by Chinese users. This corroborates the assumption that these actors are not Chinese, and may indeed be Russian, as they claim to be.

THE THREAT ACTORS’ OFFERING

The hacking services on offer are listed in more detail in another post by the same threat actors, published on this marketplace on June 15, 2020. The list of services includes:

  • Web penetration and data extraction. The actors state they have mastered the structure and special features of the main database types, such as MySQL, MSSQL, Oracle and PostgreSQL.
  • Obtaining web shells by exploiting major vulnerabilities, such as CMS, WP and Joomla, among others.
  • Cracking of software and encrypted files; secondary packaging and unpacking.
  • Software and source code secondary development.
  • Various web security-related services, such as penetration tests, code design, vulnerability scanning, emergency response, alerts and web security training, among others.

In addition to these two posts offering hacking and web-security services, in two other posts from May and June 2020, these actors also offer for sale, bots for boosting the number of “friends” and “followers” on social media networks, as well as SMS-bombing services and tools.

Finally, in recent months, we have noticed an increasing trend of Chinese threat actors operating on non-Chinese platforms. They typically use their linguistic skills and familiarity with Chinese underground platforms to make easy profits by offering data sold exclusively on Chinese platforms (usually Darknet marketplaces and Telegram groups) on English-language platforms outside China for a higher price. However, it is highly unusual to see non-Chinese actors actively operating on Chinese-language platforms. If the actors’ claim of being Russian is indeed correct, this is a relatively novel and unusual phenomenon worth noting.
